For those as ignorant as me, here's the Wikipedia explanation of what PfSense is: pfSense is an open source firewall/router computer software distribution based on FreeBSD. It is installed on a computer to make a dedicated firewall/router for a network and is noted for its reliability and offering features often only found in expensive commercial firewalls. It can be configured and upgraded through a web-based interface, and requires no knowledge of the underlying FreeBSD system to manage. pfSense is commonly deployed as a perimeter firewall, router, wireless access point, DHCP server, DNS server, and as a VPN endpoint. > https://en.wikipedia.org/wiki/PfSense https://en.wikipedia.org/wiki/PfSense
